VN Ren'Py Luna Reloaded [v0.30] [Frozen Synapse]

[ouch2020]

As for the reasons for Luna-Raven's weakening, they are quite obvious: after the nuclear apocalypse (the ending shown in “DIatima Isekai”, a game set approximately 20 years after the canon ending of LFFG and which is formally a prequel to “Luna Reborn”), centuries spent asleep, during which the remnants of the planet's surviving population diligently degraded to a medieval state, and the believers of the Goddess Raven practically disappeared, clearly did not contribute to the strengthening of Raven's divine power and greatly weakened her.

Therefore, when, centuries later, Luna-Raven finally awoke from her sleep, we naturally got a greatly weakened Luna, who did not remember her past and was not yet capable of supernatural manifestations of Divinity power. You can also read this post #776 , it complements what is written here.

Lokom85 to add up and complement (notice I probably have a different approach from Stan5851 about Luna, so, if I reinforce something he wrote, is for a logical reason, not to "support a fellow faithful"), if you look at the game variables and events, you will see that aside and independently from the "sacrifices" or not, how much diffused is the Raven cult is something that is tracked by the game in a specific variable.
You can even have zero sacrifices, and nonetheless have that value above zero, depending on how you behave in the game (in short, if you try to defend the Ravenites giving them a possibility to continue their worship, dedicate the victory at the mines to the Raven, let the Ravenites from the land of the Baron come to Cliftonhold and worship there).
So, in the overall balance of the game, my guess is in the endings or in situations later in the game, that value will have an impact, independently from the divinity points , that are more like a "currency" you can spend in specific moments.
